Paleozoic Era

This is the first era of 3 in the Phanerozoic Eon. It marks a big change in life, especially in the Cambrian Period.

This period marked many changes in life. It features complex arthropods and plants, as well as some early amphibians. Trilobites were the most known from this era.

Many continental activity happened in this era, such as Pannotia, Gondwana, Laurentia and others.

The glaciation of Gondwana happened on this era as well.

Temperatures during this time were relatively warm. Most life was in the ocean, but some lifeforms began to crawl onto land towards the end. The earliest of dinosaurs and reptiles appeared in the late Permian.

This was the era with the most periods, 6.
